CAR-FRAME CONSTRUCTION.

Specification of Letters Patent.

Patented Dec. 2, 1913.

Application led November 8, 1912. Serial No. 730,220.

new and useful Improvement in Car-Frame l Construction, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming a partof this specification, in which- Figure 1 is a front elevational view ofa car end frame showing certain features of my improved construction.Fig. 2 is a plan View partly in section taken on line 2-'2 of Fig. 1.Fig. 3 is a side elevational view looking at the right hand side of Fig.1, and illustrating the application of the device t0 the car platformframe. Fig. 4 is a side elevation partly in section on line 4 4 of Fig.1.

This invent-ion relates generally to railway car construction, and morespecifically to the one-piece, cast metal car end frames of the typedisclosed in Patent #917,716, issued April 6, 1909, and #929,705, issuedto me August 3, 1909. One of the most important features in theconstruction of the present types of railway cars, and particularlythose used for the transportation of passengers, mail and express matterand baggage, is the reinforcing of the ends of the cars so as to providean exceptionally strong and rigid construction which will efl'ectuallyresist end shocks and crushing stresses delivered to the ends of thecars. The purpose of such construction is to overcome the tendency ofthe cars to telescope in case of collisions and to afford the greatestpossible degree of safety to the occupants and contents of the cars.

My improvement contemplates a comparatively light-weight, strong anddurable onepiece cast metal structure, formed, braced and connected tothe car underframe and superstructure so as to combine therewith inresisting end shocks and crushing stresses imparted to the end of thecar, thereby pro viding a construction which is anti-telescopic ineffect.

One object of my invention is to provide an end frame of the sortdescribed having formed therein end door posts cast with parts speciallyformed to accommodate the vestibule diaphragm, and to provide parts onthe end frame specially formed to accommodate the supports of thevestibule diaphragm. y

Another object of my invention is to provide in an end frame of theclass described which is cast with integral upright and transversemembers, specially formed parts which are adapted to accommodate andsupport the shaft of the hand wheel brake or similar Vworking, parts ofthe car equipment.

By reference to the drawing it will be seen that my inventioncontemplates an integrally cast end frame having the lower member 1, theupper member 2, door posts 4, upright members 5 and transverse members6. The end frame as shown is provided with a central door opening, andis adapted for use in passenger cars and others employing the end door,the door posts are formed with deep web portions 7 and nished at theirouter extremities with the broad facing flanges 8. The flanges 8 affordan attaching place for the vestibule diaphragm 9 illustrated in Fig. 2,which is secured thereto by stay strips 10 bolted to the flanges 8 bythe bolts 11. The upper transverse member as shown in these iig-4 uresis provided with the fianges or brackets 12 in whichare formed theapertures 14 which are provided to accommodate the stems of thediaphragm buffers. Formed on the upright or transverse members of theend frame to one side of the door opening are the flanges or brackets 15in which are provided the apertures 16. These apertured ianges areprovided for the purpose of accommodating the shafts for the hand brakewhich is positioned at the end of the car.

From the foregoing it is obvious that my improved car constructionprovides a structure which is particularly adapted to prevent telescopicmovement of the end frame relative to the underframe, and that theseveral features described especially adapt cast steel end frames to theaccommodation of various elements of the car equipment.

I am aware that by changes other forms of my invention may be produced,and I therefore do not intend that my invention be limited to thespecific forni shown and described, but that it be construed to coverall obvious changes and modications.

I claiml. In car construction, an integrally cast end frame formed withupright and trans verse members, a pair of the upright meinbersperforming the functionsof door posts, brackets integral with said doorposts at predetermined points near their upper ends,

and which brackets are perforated to receive the diaphragm buiiferstems.

2. In car construction, an integrally cast Y end frame formed withupright and transverse members, brackets formed integral With certain ofsaid upright members at predetermined points, and which brackets areperforated to provide bearings -for the diaphragm buffer stems, and thehand brake shafts.

4. `In car construction, an integrally cast end frame, provided With anend door opening, door posts integral with said frame at the sides ofsaid door opening, which door posts are substantially Wider thantheWidth oit' the end frame, and laterally projecting flanges integral withthe outer ends of said door posts, which flanges `are adapted to receivethe inner ends 'of the flexible 4diaphragm.

In testimony whereof I hereunto aiiix my signature inthe presence of twoWitnesses, this 22d day of'ctober, 1912.
